Sheffield Wednesday have reportedly given manager Carlos Carvalhal one game to save his job.
The Owls are without a win in their last five matches, having fallen to a 3-1 defeat at Norwich City last weekend.
Up next for Wednesday is Friday's Championship home fixture with table-topping Wolverhampton Wanderers, a game in which Carvalhal will be serving a touchline ban.
According to the Birmingham Mail, defeat to Wolves at Hillsborough could see Carvalhal sacked after two-and-a-half years in the job.
Wednesday lie 14th in the Championship table on 27 points, 10 points behind city rivals Sheffield United in sixth place.
